I have to find the maximum of a function:
fc1= (log(c1)+alpha*log((e-c1)/p))
i need to write a code to find its gradient and hessian matrix, and after that to solve it with Newton's Method, can anyone help me?
thank you

Yes, probably. Elaborate on the problem you've encountered.

I have to solve problem 1.2. To solve it via Newton's Method, i need to firstly have the Hessian. what i don't know is how to construct this Hessian matrix.

The following link provides information about Hessian Matrix for a scalar function: https://www.mathworks.com/help/symbolic/hessian.html#buiej1q-2 . However, I believe you need to have access to Symbolic Math Toolbox to invoke this.
Otherwise, the function is relatively straight-forward for you to derive the corresponding Jacobian. So, I would suggest derive the Jacobian first and then implement it within the Newton's Method (using MATLAB).
Good luck.
